The ProTrip Trip Unit mounts on the lower right side of
the breaker. The trip unit, mounting plate, support
bracket, and wiring harness are shown in Figure 12.

harness.
1. For an electrically operated breaker, attach the X
Relay to the inside of the trip unit support bracket
with the three #10 screws and lock washers
provided, as illustrated in Figures 14 and 15. Be sure
to install the insulating shield between the relay and
the support bracket, as shown.
2. Modify the X Relay harness by adding 16-gauge
extension wire, splices, and ring terminals, as
provided. Work one wire at a time. Route the wires
as shown in Figure 5, ensuring that the wires do not
interfere with the closing solenoid plunger or the trip
unit.
3. Mount the support bracket to the two tapped holes on
the right side of the breaker with the screws and lock
washers provided, as in Figure 13 for a manually
operated breaker and in Figure 14 for an electrically
operated breaker.
